PlatformNotSupportedException thrown in MAUI on macOS when connecting Azure IoT Hub

I am exploring MAUI on macOS. I am porting a WPF application to evaluate the functionalities. The application is connecting to an Azure IoT Hub instance.

Here is the section of code that seems problematic:

var iotHubConnectionStringBuilder = IotHubConnectionStringBuilder.Create("HostName=<iotHubConnectionString>");

var registryManager = RegistryManager.CreateFromConnectionString(iotHubConnectionStringBuilder.ToString());

When calling CreateFromConnectionString, the following exception is thrown:

    Unhandled Exception:
           System.PlatformNotSupportedException: Operation is not supported on this platform.

I have played with the different HttpClient implementation without any positive outcome. And, surprinsingly enough, it exhibits the same callstack, with NSUrlSessionHandler.set_SslProtocols on top of it:

Question

Why is this error thrown and how can it be fixed?

Solution

I was using Visual Studio 2022 for Mac version 17.3 Preview 1. After updating to Visual Studio 2022 for Mac v17.3 Preview 1.1 as well as the .net MAUI workload, it worked.

I let the HttpClient implementation to NSUrlSession.

I am not sure the exact reason why it works now but I assume these issues are bound to happen when using preview products.
